LOCK.

@PECFIGATEQN forming part of Letters Patent No. 309,181, dated December 9, 1884. Application filed April 11, 1884. (No model.)

To all whom. t may concern:

Be it known that we, RUDOLF E. VOOD- nien, of the city, county, and State of New York, and CHARLES LANG-REIN, of Brooklyn, in the county of Kings and State of New York, have invented a newand Improved Lock, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved lock which can be secured and held in place without the use of screws, and which can be adjusted at different lengths, and can also be adjusted in such a manner that it cannot be unlocked from the outside.

The invention, which is an improvement on the lock for which Letters PatentmNo. 294,56() were issued to us on the Lith day of March, 1884, consists in the construction and arrange nient of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specication, in which similar letters of reference indicate cor responding parts in all the figures.

Figure l is a longitudinal sectional elevation of our improved lock, showing the bolt drawn within the casing. Fig. 2 is a longitudinal sectional elevation of the same, showing the bolt thrown out. Fig. 3 is a similar sectional view showing1 the plate locked in such a position that it cannot be opened from the outside. Fig. 4, is a cross-sectional elevation of the lock, showing the arrangement of the bolt, spindle, and key. Fig. 5 is a face view of the inner side of the neck for guiding the key. Fig. Gis a side view of the saine. Fig. 7 is an end view of the slitted barrel for receiving the key. Fig. S is a plan view of the guard in the neck for guiding the key. Fig. 9 is an inner iace view ofthe guide-neck and the plug in the same.

The lock is constructed with a cylindrical casing, A, closed at the lower end andopen at the upper end, over which casing a cylindrical cap, B, is held, which is provided with an aperture through which the sliding bolt C can pass. The cylindrical cap B is held in place by means of screws a, passed through the inner end of the said cap and through the casing A, and by means of which screws the cap can be held on the casing in such a manner that the apertured end of the cap will be held a greater or less distance from the open end ofthe casing. There will be a series ot' holes in the casing arranged at certain distances apart for the screws c to engage to secure the cap in its adjustment on the said casing. By means of the cap the casing can belengthened or shortened, as may be desired. The bolt C is provided at its base or inner end with an annular flange, C, between which and the apertured end piece of the cap B a spiral spring, D, is held,which surrounds the bolt an d presses the same inward. The bolt is provided in its inner end with a screw-threaded aperture, E, into which a screw, F, is screwed, which is provided with a semispherical or like rounded head, F. The lock-casing is provided in its lower end with a vertical slot, G, in the middle of which a partition, G', projects up-A ward from the bottom of the easing, on which partition a cani-plate, H, is pivoted, which camplate is provided in its bottom edge with a groove, H, adapted to receive the partition or standard G. The cam-plate is provided in its straight edge with a notch, h, into which a cross-screw, I, of thecasing passes, as shown in Fig. l, when the bolt is within the casing. rlhe said cross-screw I limits and cheeks the movements of the cam plate or disk H when the same is raised or lowered, as shown in Figs. l and 2. A iiat spring, J, is secured to the bottom of the casing at one end of the slot G, extends across the bottom of the slot, and has its end J bent up in the shape of the letter S, 'which spring J rests against the cam-edge of the disk H at about the middle of the length ofthe horizontal part ofthe said spring. The casing A is provided in one side with a screw threaded aperture, b, into which is screwed the externally-screw-threaded end of a sleeve, K, containing the knob-spindle L, on the outer end of which is the knob L. rIhe knob-spindle L is provided with an annular groove, Z, for receiving the end of a screw, 7c, which is passed through the sleeve K, and serves to hold the said spindle in the sleeve in such a manner that the said spindle can re Cil volve on itsv longitudinal axis, but cannot move in the direction of the length of the same. Around the aperture b an annular recess, c, is formed for receiving the end. of a collar, M, formed on and projecting' from the inner end of an escutcheon-plate, M, which collar M is screw-threaded internally, and is screwed on the sleeve K at the inner end. The spindle L is provided at its inner end with two teeth, m, which pass into corresponding apertures or notches in the side of the cani-plate H. On that side of the casing opposite the one in which the knob-spindle is held a recess, d, is formed for receiving the end of a neck, 0. In the middle of the recess cl an aperture is formed for receiving the end of a locking-plug, P, held to revolve on its longitudinal axis in the niiddle ofthe neck O. The neck O is held in place by the pin or screw I, which is screwed through the casing from the inside, so that its threaded end, after passing through the casing, passes into the inner end of the neck O, and holds the saine on the casing, thus preventing burglars or others from removing the neck O from the casing from the outside. The neck O is provided on its inner end with an annular flange or ridge, a, in which a recessed part, n', is formed, the ridge being formed around the inner edge of the opening for the plug P. The plug l is provided with a transverse slot, F', extending i'roni end to end,`and the said plug is provided at its inner end with a short pin, o, which rests on the recessed part n of the inner edge ofthe iiange n. The plug is also provided with a pin, lt', which extends through the slot l a greater or less distance from the inner end of the plug. rlhe neck O 'is provided with atriangular or other shaped guard, S, which projects into the opening in the neck and into a transverse slot in the plug l?. The key T is provided at its inner end with a longitudinal notch, l', for receiving the transverse pin R in the plug, and is Aalso provided in its side edges with notches s, for permitting the guard S to pass. The guard S can be of diiierent shapes and sizes 'for the different locks. The rounded edge ofthe cam-disk H is provided with an offset, t, against which the end ofthe S-shaped part J of the spring J rests when the bolt is in the casing, and said edge is also provided with an offset, w, against which the end of the part J of the spring J can rest when the lock is adjusted in such a manner that the bolt cannot be withdrawn fromthe outside. f

The operation is as follows: rlhe inortise is made in the edge of the door. s The lock-casing A is placed in the inortise in such a inanner that the outer end of the cap B is iiush with the edge of the door. Openings are made in the side surfaces of the door for receiving the knob-spindle and the neck O, the outer end plate, Q, of which neck must be ilush with the outer surface of the door. rlhe cap B is suitably adjusted on the casing, and the bolt C, is adjusted in such a manner that its outer end will be ilush with the end of the cap B when the bolt is withdrawn into the casing. The bolt is adjusted in length by turning the screw F in such a ina-nner that it projects a greater or less distance from the base end of the bolt. The tension of the spring D alwaysremains the same, as the length between the inner surface of the top .of the cap and the ange C of the bolt is uniform, but the screw F projects a greater distance from the inner end of the bolt when the bolt is lengthened than when the bolt is shortened. After the casing has been placed in the niortise in the door the inner end of the neck O is placed in the recess d in lthe casing, and is held in place by the screw or pin l, the sleeve K is screwed into the opposite end of the casing on the inside of the door, and the escutcheon plate M is screwed up against the surface of, the door. "When the bolt is withdrawn, the cani-plate H is in the position shown in Fig. l. If the cam-plate is turned in the direction of the arrow a', Fig. 1, its edge acts on the rounded head F of the screw F in the bolt, thus throwing the bolt outward, as shown in Fig. 2, in the same manner as the bolt is thrown by turning the spindle. It can be thrown by means of the key T, which is introduced in the slotted plug l?, and is provided'at its inner end with teeth a, which pass into notches in the cam-plate H. If the key is turned, the guard S passes through the'slot or notch s in thekey. If the lock is to be-so adjusted from the inside that the bolt cannot be withdrawn by means of the key, the cani-plate is thrown,

in the 4direction of the arrow a until the end ofthe part J of the spring J rests inthe notch or offset win the curved edge of the cam-plate; or, if the cani-plate H is in the position shown in Fig. 2, it is turned back in the inverse direction of the arrow a until the end of the part J of the spring J rests in the notch w, as shown in Fig. 3. If the key is introduced when the cam-disk H is in the position shown in Fig. 2, the guard S is in such a position that the prongs u of the key (shown in cross-section in Fig. 2) can pass the edge of the guard IOO S, which is shown in dotted lines; but if the cani plate or disk H is turned in such a manner that the end of the part J of the spring J rests in the notch or oi'set w the notches-p, formed in the side of the disk H for receiving the teeth of thekey, will be in such a position that the guard S will be between one of the said notches and the slot in the plug P-that is, if the plug P is turned in such a manner that its slot P is in line with thetwo notches p, the guard S prevents the teeth of .the key from passing into the said notches.

If the .plug l? is turned in such a manner that its slot will be in line with the edge of the guard S, so that the end of the key can pass the guard, then the teeth of the key will not be in line with the notches P, and thus cannot be passed into the same; or, ein other words, if the cani-disk H is adjusted in such a manner l will be adjusted in such a manner that the key cannot be introduced effectively from the outside. By simply adjusting the cain-disk I-I the lock is made absolutely safe and burglarproof, as it is impossible to change the position of the camdisk from the outside without cutting out the door. rIhe lock is held in place by the neck O and the sleeve ofthe k nob-spindle, and is not screwed into the door. The lock inust be secured in 4place from the inside of the door, and can only be removed from the inside, as the pin or screw I holds the neck O on the casing. By varying the position of the pin R in the slotl?l of the plug P the lock will be changed to such an extent that the key oit' another lock cannot be used.

Instead of using only one guard, S, several guards can be used the saine as in other locks.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In a lock, the combination, with the Casing A, ot' the adjustable cap B, the bolt C, having a flange, C, at its lower end, the spring D, held between the said flange and the end ot' the cap,l a screw screwed into the lower end of the bolt, and an operating-earn coustructcd to bear against the end of the bolt for throwing the bolt, Substantially as herein shown and deseribcd. l

2. The eonibinatio1i,witl1 a lock-casing containing a bolt, of a cani-disk for acting on the bolt, a spindle projecting' from one side of the casing and connected with one side ofthe cant disk, and of' a neck projecting from the oppo site side of theloekeasing and provided with a revolving key-guide disconnected entirely from the boltoperating mechanism, substantially as herein shown and described.

3. The combination, with a sliding bolt mounted in a casing having its outer key-hole provided with a guard, of an operating-cani pivoted in rear thereof, said cani being constructed with keyapertures on its opposite DIZ sides and with offsets on its lower edge, substantially as shown, and a horizontal spring engaging the plain edge of the cani and provided with an 'upward curved projection adapted to engage said offsets, whereby when the cani is arranged with one otit-s offsets engaged by the upward bent part of the spring it will be held from turning and its outer key aperture be held behind the guard, substantially as set forth.

4. In a lock, the combination, with the easing, ol' the sliding bolt, a pivoted cam-disk, a neck held to and projecting troni one side of the casing, and a longitudinally-slotted plug or key-guide held to revolvein the said neck, which neck is held on the casing by a screw or pin, I, passed through the casing from the inside and extending into t-he said neck O, substantially as herein shown and described.
